Welcome to the Madrigal Database at Haystack Observatory

Madrigal is an upper atmospheric science database used by groups throughout
the world. Madrigal is a robust, World Wide Web based system capable of managing
and serving archival and real-time data, in a variety of formats, from
a wide range of upper atmospheric science instruments. Data at each Madrigal site is locally
controlled and can be updated at any time, but shared metadata between Madrigal
sites allow searching of all Madrigal sites at once from any Madrigal site.
